The term 'vole' is a type of small mammal that belongs to the RODENT family. It is related to other rodents such as mice and rats, which have 5 and 3 letters respectively. Voles are also known as field mice or meadow mice and are found in many parts of the world. They are typically smaller than rats and mice, and have short tails and rounded ears. Voles are omnivorous, meaning they eat both plants and animals. They are often considered pests due to their habit of burrowing and eating crops.
